Title: Solid-gas separator
Inventor: OOKI ICHIROU
IPC: B01D45/08
Filed: 1978-08-01
Abstract: PURPOSE: To force abrupt direction change to the gas being passed and let solid- gas separation be effectively accomplished by bending a rectangular plate from the center, bisecting its inner side and parallel installing two closing plates on the outer side to form a unit baffle plate and parallel placing a plurality of these thereby forming crooked paths.  
     CONSTITUTION: The central part of a rectangular plate 1 made of stainless steel is bent nearly at 90° in parallel with its long edges and the inner side thereof is bisected longitudinally by a segment plate 2. Closing plates 3, 4 are protrusively provided in parallel with the segment plate 2 at 1/3 the width of the plate 1 on the outer side to make a unit baffle plate A. Next, a plurality of these plates are so parallel and longitudinally placed within a holding frame 5 of rectangular parallelopiped that the ends of the adjoining segment plates and the ends of the closing plates mutually overlap, whereby the crooked paths for air are formed. The bent edges of the plates 1 are inserted and held in the notched grooves of the inner edge parts of the holding plates 6 secured to the upper and lower inside edges of the holding frame 5. Since the air passing the crooked paths is changed of directions, the particles contained thereon stall or collide against the plates and are thereby efficiently separated.

Title: Optical second harmonic wave generating element and production thereof
Inventor: MORITA YUKIO
IPC: G02F1/361
Filed: 1988-04-16
Abstract: PURPOSE:To improve conversion efficiency by orienting and crystallizing an org. nonlinear optical material incorporated in a waveguide by impression of a voltage thereto, then converting the incident light on one end of the waveguide to a second harmonic wave, releasing the wave from the other and confining the incident light. CONSTITUTION:The optical second harmonic wave generating element is constituted by providing electrodes 1, 3 on the waveguide layer 2. The element is so formed that laser light of a wavelength lambda is projected to the waveguide from one end thereof and the light of 1/2.lambda wavelength is taken out. The wavelength conversion is executed by the oriented and crystallized org. nonlinear optical material in the waveguide. The orientation and crystallization are executed by impressing the DC voltage to the upper and lower electrodes of the waveguide layer. The voltage of about 1V/mum suffices. A Cerenkov radiation system which can take automatic phase matching is adopted to the waveguide as the efficiency is higher with this waveguide if the phases of the incident light (wavelength lambda) and the taken-out light (wavelength 0.5lambda) are matched. The incident light is confined in the waveguide and the state of high energy density is attained. The conversion efficiency is proportionally improved. The org. nonlinear optical material has a less tendency to deterioration in properties. The orientation and crystallization are reproduced by impression of the voltage.

Title: Snubber energy regenerative circuit
Inventor: ONABE MINORU
IPC: H02M1/06
Filed: 1994-05-06
Abstract: PURPOSE:To make a snubber energy regenerative circuit usable at a high frequency by simultaneously turning on an auxiliary self-arc-extinguishing element with a main self-arc-extinguishing element by connecting the electric charge of a snubber capacitor in series with the former and an alternating device or reactor and, after completing regeneration, turning off the former before turning off the latter. CONSTITUTION:When a main GTO element G1 and auxiliary GTO element Gs1 are simultaneously turned on from turned-off states, the electric charge of a snubber capacitor C1 is discharged through a closed circuit of C1-G1-CT1-Gs1-C1 and a discharge current is generated. At the same time, a secondary current which regenerates the energy of the capacitor C1 to a DC power source side flows from the secondary side of a current transformer CT1. After the DC voltage across the snubber capacitor becomes zero, the primary current of the transformer CT1 forms a closed circuit of CT1-Gs1-D1-CT1 and a circulating current is generated by stored energy. When the main GTO element G1 is turned off thereafter, the resetting current of the transformer CT1 abruptly decreases and the resetting period of the transformer CT1 can be shortened, since the potentials at the transformer CT1 and capacitor C1 rise. Therefore, this snubber energy regenerative circuit can be applied to a high frequency.

IPC: H04N5/92
Filed: 1985-05-02
Abstract: PURPOSE:To execute switching automatically without executing it manually and to save a trouble for switching by providing a switch for switching a device to one of a usual recording system and a high band recording system in accordance with an output of a voltage comparator for comparing an output voltage of an FM demodulator with a reference voltage. CONSTITUTION:A comparator is used as a voltage comparator, and as for a voltage of a point (c), as a modulation range of a recording frequency is shifted to a higher frequency, a voltage of a demodulated video signal becomes high. A voltage of a point (d) is set by split resistances 162, 163 and becomes a reference voltage. When a higher voltage than this reference voltage is detected in the point (c), an output of the comparator of a point (e) becomes a high level, and by this high level, switches 19, 20 are switched to a side (a), and a trimmer capacitor 13 and an LPF 17 for a high band system are selected. On the contrary, when a low voltage is detected, the output of the comparator of the point (e) becomes a low level, the switches 19, 20 are switched to a side (b), and a trimmer capacitor 14 and an LPF 18 are selected. In this way, when executing a reproduction, the high band system or a conventional system can be switched automatically.

Title: Mfb speaker system
Inventor: TAKEMURA KAZUNARI
IPC: H03F3/45
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce non-liner distortion by providing a speaker always having an ideal voice coil vibration center by inserting 1st and 2nd average value filters for averaging respective outputs on the following stages of a displacement detecting means and a filter means. SOLUTION: On the rear stages of the digital filter 4 and the displacement detection sensor 2, 1st and 2nd average value filters 7 and 8 are respectively inserted. When displacement characteristics are inserted to the average value filter 7, its output shows the average position of the vibration system, namely, a central position in the displacement of vibration. In this case, when a distorted component at the time of even number exists at the real speaker, the central position in the displacement of the voice coil is deviated back and forth because of its influence. Therefore, when a signal detected by the displacement detection sensor 2 is inputted to the average value filter 7, its output applies the deviated central position in the vibration.  Since the output of the digital filter 4 is a linear response, on the other hand, no distorted component exists and when a signal is a pure tone, for example, the displaced output passed through the average value filter 8 is turned to zero.
